Time frame: From first participant until last participant assessment, an average of 8 months
Percentage of patients whose best overall response is either a Complete Response or a Partial Response according to Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST 1.1) criteria over the total number of evaluable patients
Disease control rate (DCR)
Time frame: From first participant until last participant assessment, an average of 8 months
Percentage of patients whose best overall response is either a Complete Response, a Partial Response or Stable Disease according to Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST 1.1) criteria over the total number of evaluable patients.
Duration of overall Response (DoR) by RECIST version 1.1
Time frame: From first participant until last participant assessment, an average of 8 months
Time from the date of first documented response (CR or PR) to the date of first documented disease progression according to RECIST 1.1 criteria or the date of death due to underlying cancer.
Progression Free Survival (PFS) by RECIST version 1.1
Time frame: From first participant until last participant assessment, an average of 8 months
Time from the first infusion of LB1410 and LB4330 to the date of first documented tumor progression according to RECIST 1.1 criteria or death due to any cause, whichever occurs first over evaluable patients.
DDC
Time frame: From first participant until last participant assessment, an average of 8 months
Time from the date of first documented CR, PR or SD to the date of first documented disease progression according to RECIST 1.1 criteria or the date of death due to any cause.
Overall Survival (OS) duration
Time frame: From first participant until last participant assessment, an average of 1 year
Time from first LB1410 and LB4330 infusion to the date of death due to any cause over evaluable patients.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing LB1410 and LB4330 in people with Solid Tumor, run by L & L Bio Co., Ltd., Ningbo, China at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 68 inclusion and 36 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 11 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Yan Luan (+86-21-54152522, luanyn2@lnlbio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety and tolerability (Adverse Event reported per NCI-CTCAE v5.0) (time frame: up to 60 days following last dose). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Sep 2025.
